摘要：
The Xidatan rock series consist of mylonite, gneiss and granite. The U-Pb age shows that the granite was formed at 206 Ma, and the 40Ar/39Ar ages of the biotite display that the mylonite was formed at 145 Ma when the Xidatan ductile shear zone occurred. At about 110-100 Ma, the Xidatan Fault reactivated again. As a result, the biotite and muscovite of Xidatan rock series opened their argon isotope system.
